Over the last three decades, a number of researchers have used the gradient-enhanced
plasticity theory to model the microstructural material behavior, which is not able to be …

This work presents an introduction to popular damage and fracture models along with the
major breakthroughs and the current state of the art. The theoretical and computational …

A overview is given of different approaches to simulate and predict crack propagation in
quasi-brittle materials, pointing out their merits, disadvantages and complementarity …

Damage initiation and propagation in a class of non-local and gradient-enhanced media is
investigated. In this contribution it is shown how the use of a non-local dissipation-driving …

This paper presents a framework for modeling failure in quasi-brittle geomaterials under
different loading conditions. A micromechanics-based model is proposed in which the field …

This paper presents a novel variational phase-field model for different fracture processes in
fully saturated porous media. As a key feature, the model employs a micromechanics-based …

Gradient theories, as a regularized continuum mechanics approach, have found wide
applications for modeling strain localization failure process. This paper presents a second …

This work is concerned with the precise characterization of the elastic fields due to a
spherical inclusion embedded within a spherical representative volume element (RVE). The …

Nonlocal implicit gradient enhancements are widely used to suppress mesh dependency in
simulations involving strain localization. For example, nonlocality is often introduced through …

The original model proposed present many advantages for applications which require
cracks opening and reclosure management. It is easy to implement in most of the finite …
